Packet 2: Bonus 4

This statement formalizes the law of conservation of energy for circuits. For 10 points each:
[10m] Name this law in circuit analysis that states that the sum of all potential differences around a closed circuit path is zero.
ANSWER: loop rule [or Kirchhoff’s loop rule or Kirchhoff’s voltage rule; accept Kirchhoff’s second law or Kirchhoff’s second rule or answers suggesting the latter of two rules devised by Kirchhoff; prompt on Kirchhoff’s rule or Kirchhoff’s law or Kirchhoff’s circuit law or Kirchhoff’s circuit rule]
[10h] The loop rule holds if this operation applied to the electric field in a circuit is zero, implying the electric force is conservative. This operation applied to the vector potential gives the magnetic field.
ANSWER: curl [accept del cross; reject “del”]
[10e] Circuit analysis uses the loop rule alongside the junction rule, which states that the amount of this quantity entering equals the amount of this quantity exiting a junction. This quantity is measured in amperes.
ANSWER: current [or I]
